PAPER-CUTTER.

To all whom it may concern:

Be it known that I, LoUIs A. Rnisnn, a citizen of the United States,residing at lVaterbury, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inPaper-Cutters, of which the following is a specification.

This invention relates to what are known as paper cutters and a papercutter comprising my invention can be used with advantage in manydifferent connections, it being particularly useful in cutting wallpaper. all paperers generally use a cutter comprising a shank equippedat one end with a handle and at the other with a rotary cutting memberwhich is usually made in the form of a peripherally toothed or serratedwheel. In operation the handle is grasped and the wheel is rolled alongthe paper to be out, the teeth thereof scoring the paper or making aweakened line to facilitate the separation of the paper into twoportions.

A cutter of this old type possesses certain defects which are eliminatedby my cutter. \Vith the old cutter it is rather a difiicult matter to soweaken the paper by the score lines that it can be torn or separatedcleanly along such lines, this being especially true when the paper ismoist which is invariably so with wall papers. My cutter comprises twocutting members which converge in a forward direction and owing to thisconvergence, I find that there is a tendency on the part of the cuttingmembers to separate the paper just back of the active portion of thecutting mechanism. I find that I can secure the best results byemploying two wheels which are rotatably supported and which may beconnected with any suitable type of carrier, for instance, a shank suchas that now found in the ordinary paper cutter. These wheels preferablyjointly make the cut and this result is best assured by meshing thewheels for a portionof their peripheries so that they turn in unison andI find that by this meshing I can make a well defined pronounced scoreline, although the same result could probably be secured by dispensingwith the mesh, although, as intimated, this relation is preferable.There may be cases where I might wish to use but one of the wheels at atime, and in this event the device would be so tipped as to bring butthe one selected into action. Under or- Specification of Letters Patent.

Application filed March 31, 1910.

Serial No. 552,516.

I dinary circumstances, however, they operate together.

In the drawings accompanying and forming part of the presentspecification, I have embodiment of the invention which to enable thoseskilled in the art to practice the same will be set forth fully in thefollowing description, while the novelty of the invention will beincluded in the claims succeeding said description. From what I havestated, it will be evident that I do not restrict myself to thedisclosure made by said drawings and description for I may departtherefrom within the scope of my invention as expressed in said claims.

Referring to said drawings: Figure 1 is a side elevation of a papercutter including my invention, and, Fig. 2 is an elevation at rightangles to that shown in Fig. 1 and partially in section.

Like characters refer to like parts in both figures.

The device in the present case includes cutting mechanism and a suitablecarrier therefor and while the carrier may be of any suitable type, ashank such as 2 answers satisfactorily in this respect, the same beingequipped at its outer end with a handle 3. There are two cutting wheelsas 4 and 5, and they are angularly disposed with respect to each other,converging in the present case in a forward direction and preferably asalready indicated being in meshed relation the place of meshconstituting the actual cutting or scoring portion. The pivots for thewheels are denoted respectively by 6 and 7, and they may as shown,consist of screws tapped into the forward end portion of the shank 2which may be made of any suitable material as may be the two cutters.The central portions of the two wheels fit against the forwardlyconverging flattened faces 8 and 9 by virtue of which wabbling motion ofthe cutters is not possible. The wheels preferably turn in unison andwhile there are probably several ways in which this result can beobtained, I find that it can be in a simple manner by meshing the twowheels and this can be accomplished by slightly laterally deflecting theteeth inwardly.

The device can be held at various angles represented in detail onesimple form of or vertically, and the place of mesh of the which whenthe cutter is held vertically the two wheels will jointly cut a decidedand pronounced score line whereby the paper can be readily separated bya slight pull without any possibility of the same bein irregularly torn.The tool can also be tipped at a slight angle to the vertical and inthis event the two wheels out a slightly wider score than when the toolis vertical but when the implement is held at the angle indicated notonly is a scored line produced but the actual tendency of the wheels isto spread the paper apart just-back of the cutting location and in thisparticular event no pull is necessary on the paper.

What I claim is:

1. A device of the class described comprising a shank having forwardlyconverging flattened faces, and a pair of rotative cutters fittedagainst said flattened faces and peripherally toothed, the teeth of thecutters beinglaterally in mesh for a portion of the circumferences ofthe respective cutters.

2. A paper cutter comprising a shank provided with a handle and alsoprovided with two cutters angularly disposed with respect to each other,each cutter having peripheral scoring teeth and said teeth beinglaterally in mesh for a portion of the circumferences of the saidcutters.

In testimony whereof I affix my signature in presence of two witnesses.
